I am a Batrachologist with special interest in the field of behavioural ecology, landscape ecology, movement ecology and urban ecology. I teach fundamentals of ecology, biostatistics and remotesening and GIS. I also work with citizen scientists in spreading awareness about amphibians and in collecting data for long term monitoring programmes.

citizens. This species was identified to be distinct based on molecular and morphological evidence. We provide a detailed description of this species along with its call description and compare it with closest congeners. Previous studies in the region had identified this species as E. hexadactylus but suggested the possibility of it being cryptic. Genetically E. karaavali sp. nov. is distinct from E. hexadactylus with a genetic divergence of 9.2% (12S and 16S) and shows a high divergence with E. kalasgramensis and E. ehrenbergii (13.04% each). Our findings are discussed in the context of cryptic species discovery, citizen engagement in scientific progress and conservation measures while suggesting future directions.
keratodonts. The morphology indicates that these tadpoles are adapted to lotic habitats. In recent years, many of the streams these tadpoles inhabit have been diverted for agriculture and areca plantations. The descriptions of these tadpoles bear relevance for their conservation and can help in understanding amphibian larval ecology.
history strategies in an evolutionary framework is lacking for many amphibian species in the tropics. Here, we report
a novel reproductive mode where adult frogs enter hollow internodes of bamboo via a small opening, deposit direct
developing eggs, and provide parental care. This behaviour is observed in two species of the frog genus Raorchestes.
The first description of this unique life history and details of nest site characteristics and embryo development are
provided along with ecological comparisons. Evolution of novel reproductive modes and parental care are discussed
in context of natural selection. Dearth of natural history information on amphibians in the Western Ghats and much
of the South-East Asian region is highlighted with suggestions for further studies.

attributed to such diverse reproductive modes. Globally forty different reproductive modes in anurans have been described
to date. The genus Nyctibatrachus has been recently revised and belongs to an ancient lineage of frog families in the Western
Ghats of India. Species of this genus are known to exhibit mountain associated clade endemism and novel breeding
behaviours. The purpose of this study is to present unique reproductive behaviour, oviposition and parental care in a new
species Nyctibatrachus kumbara sp. nov. which is described in the paper. Nyctibatrachus kumbara sp. nov. is a medium
sized stream dwelling frog. It is distinct from the congeners based on a suite of morphological characters and substantially
divergent in DNA sequences of the mitochondrial 16S rRNA gene. Males exhibit parental care by mud packing the egg
clutch. Such parental care has so far not been described from any other frog species worldwide. Besides this, we emphasize
that three co-occurring congeneric species of Nyctibatrachus, namely N. jog, N. kempholeyensis and Nyctibatrachus kumbara
sp. nov. from the study site differ in breeding behaviour, which could represent a case of reproductive character displacement.
These three species are distinct in their size, call pattern, reproductive behaviour, maximum number of eggs
in a clutch, oviposition and parental care, which was evident from the statistical analysis. The study throws light on the
reproductive behaviour of Nyctibatrachus kumbara sp. nov. and associated species to understand the evolution and adaptation
of reproductive modes of anurans in general, and Nyctibatrachus in particular from the Western Ghats.
